Reaction Conditions:
hydrogenchloride at 60; for 3 h;
Steps:
2
Example 2: Methyl 2,4, 5-trifluoro mandelate 6 (R1 = CH3) Under inert atmosphere, 50 g 2, 4, 5-trifluoromandelic acid is suspended in 135 mL methanol containing 3% HCl, and the mixture is heated to 60° C for 3 hours. Once the conversion is completed (HPLC) , the mixture is cooled to room temperature, it is concentrated in vacuum, taken up again with toluene, and washed with an aqueous sodium carbonate solution. The organic layer is concentrated in vacuum, yielding 50 g (94%) of product as a light-
